Popis: We have studied the properties of Si1 − x Gex-based p-i-n structures and Schottky barriers in which the i-region had been produced via compensation with gold. The results demonstrate that the use of a guard ring in p-Si1 − xGex〈Au〉 structures reduces the room-temperature reverse leakage current by two to three orders of magnitude. Such structures have sufficiently small reverse currents and a barrier on the order of 0.75 eV. p-Si1 − xGex〈Au〉-based guard-ring structures are suitable for the fabrication of IR and nuclear detectors.
